I just picked up a used cross bike. I am coming from the mountain bike world where the trend is shorter and shorter stems and wider bars. So the bike I just got came with a 130mm stem which is way too long for me anyway you look at it and has got to go. What is the sweet spot for cross stems? I was thinking around 90mm, but it feels like I could go even shorter and be comfortable. I know the proper answer is "go get fitted", but please indulge me with anecdotal tales of your experience.
